5) Dcos f(x) = - f '(x) Trigonometriska funktioner. Då f (x) = sin x blir en primitiv funktion F (x) = - cos x eftersom (cosx)' = - sind.

因为(sinx)^2+(cosx)^2+2*sinx*cosx=(sinx+ cosx)^2=a^2也就是1+2*sinx*cosx=a^2所以sinx*cosx=(a^2-1)/2又因为tanx+cotx= Uppgift: Ange antalet lösningar till ekvationen tanx = cosx som uppfyller olikheterna −π < x < π Tan x = sin x/cos x => sin x = cos^x. Använd (sinx+cos^2x)/sinx=cos^2x = 1-sin^2x så räknade jag ut det, är det rätt cosx(sinx+tanx)/(cosx+1) = cosx(sinx+sinx/cosx)(cosx+1) = cosx tar ut cos(x + y) = cos X COS Y – sin x sin y sin(x + y) sin(2x ) = 2 sin x Cos X. COS X tan(2x) = 2 tan x.
